Abstract
Colossal Magneto Resistance (CMR) materials with the compositional formula, La0.67 −xEuxSr0.33MnO3 (where x=0.3,0.33,0.36 and 0.39x=0.3,0.33,0.36 and 0.39) were prepared by the sol–gel method. After characterizing the samples structurally, a systematic investigation of magnetization has been undertaken, over a temperature range 70–300 K under 0.05 T magnetic field. An effort has been made to calculate the magnetocaloric behavior of all the samples theoretically using the experimental magnetization data. Magnetocaloric effect parameters such as maximum entropy change, full width at half-maximum and relative cooling power under 0.05 T were computed. The observed behavior has been explained qualitatively.
